branch
Key: HDFS-4707
URL: https://issues.apache.org/jira/browse/HDFS-4707
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Tsz Wo (Nicholas), SZE
Assignee: Tsz Wo (Nicholas), SZE
The snapshot methods are not added to FilterFileSystem.
Findbugs warnings:
- SIC Should snapshot.Snapshot$Root be a _static_ inner class?
- WMI Method FSImageFormat$Saver.saveImage(ByteBuffer, INodeDirectory,
DataOutputStream, Snapshot, boolean) makes inefficient use of keySet iterator
instead of entrySet iterator
- BC Unchecked/unconfirmed cast from
FSImageSerialization.writeINodeFile(INodeFile, DataOutput, boolean)
- BC Unchecked/unconfirmed cast from
snapshot.SnapshotFSImageFormat.loadDirectoryDiffList(INodeDirectory, DataInput,
FSImageFormat$Loader)
